[GreenKeys] Model 28 FIXED!

[Mike McAuley]

Thanks Jim,That's a good thing to know. Manually advancing the mechanism that way.  Great way to trouble shoot by seeing all the action in slow motion.I ran mine through that way and typed out the letters that are showing up low.  When typed out by manually spinning the motor, they show up correctly in a nice straight line at the proper height.Only when machine is powered do they go askew and low.Mike

When all five code bits have beengenerated by the kbd, the code selection barsshould be in the proper positions -- if they are,then they are working ok; then you will have tocontinue manually rotating the motor and watchthe typebox alignment and see if it is respondingcorrectly.  This should all work in 'slow motion'as you manually rotate the motor.A code bar or other item missing a spring shouldbe spotted right away as it will not respond asit should.
